Round-the-clock alarm
 Send this article
Detecting an oil spill as soon as possible is vital to minimise its effects. The oil industry and state authorities are therefore in continuous search for improved methods to seek earliest possible detection of oil spills. They need an instrument which will automatically detect, give alarm and define the magnitude of the spread.
Oil Spill Detection System (OSD), a new technology from the Miros Wavex System allows availability of information day or night, regardless of visibility. Clean-up operations may now take place in 24-hour-round-the-clock efficiency.
The system provides an automatic alert if an oil spill is present. A user-friendly, graphical user interface shows the oil spill, its area, velocity and other information valuable for an oil recovery operation.
OSD collects digitised sea surface images from standard marine X-band radars and estimates directional wave spectra and the sea surface current.
Many high-risk oil-spill sites already have a marine X-band radar, which facilitates the availability of radar sea-clutter images. It is important to extract information about oil spills from these images. Results from previous trials with air-borne radars indicate that X-band radars are well suited for oil-spill detection. Using X-band radar makes it possible to see oil spills in the dark, enabling skimming operations to function on a 24-hour basis.
The system features a bridge display for monitoring wave parameters in real time without any need for post-processing. OSD is based on the Wavex system and on the fact that areas covered by oil will reflect less microwave power due to dampening of sea surface capillary waves.
